Instead of using new technologies to preserve for ready discovery material that might in the past never have been stored, or deleting everything as soon as possible, we can develop systems that place sensitive information beyond reach until a specified amount of time has passed or other conditions are met.

I'm interested in helping secure the PC - we need innovation here. It's not just hug your PC, hate the iPhone. In fact I don't even hate the iPhone; I think it's really cool. I just don't want it to be the center of the ecosystem along with the Web 2.0 apps.

The last refuge of privacy cannot be placed solely in law or technology. It must repose in both, and a thoughtful combination of the two can help us thread a path between having all our secrets trivially discoverable and preserving nothing for our later selves for fear of that discovery.

Attacks on Internet sites and infrastructure, and the compromise of secure information, pose a particularly tricky problem because it is usually impossible to trace an attack back to its instigator.

With digital space, the content has become accessible for the audience. So, they feel more connected to you as you are more accessible to them. The kind of adulation actors get today is very different from the kind of adulation you had for a star which came from aspiration rather than relatability.

I've been fascinated by the Internet from the very start. In 2001, I had made a funny black-and-white film called 'How to Dance Properly,' a short video of me dancing to a Madonna song. I sent it to 17 of my friends on a Thursday, and by Monday, one million people a day were logging on to view it.

In 1958, my father graduated from secondary school as the highest-achieving student in the state of Kansas, earning a five-year scholarship to the Massachusetts Institute of Technology. He turned it down. For someone raised in a remote farming town, this would have been his opportunity to transform his life, a ticket to a bigger world.

China is a great manufacturing center, but it's actually mostly an assembly plant. So it assembles parts and components, high technology that comes from the surrounding industrial - more advanced industrial centers - Japan, Taiwan, South Korea, Singapore, the United States, Europe - and it basically assembles them.
